But he said there are plenty of challenges for them ahead as learning protocol and how to deal with the attention is "a pretty tough act".

He also told People magazine that the duo seems to be "having a good deal of access so far", but that "sooner or later, she's going to face the full onslaught".

The Prince, who married Olympic swimmer Charlene Wittstock in 2011, was referring to the even more intense scrutiny Meghan will face if she marries Harry.

The Monaco royal added: “I can’t imagine how that will be on them, on her.

“Being an actress, in a way, gets you a little prepared but nothing really can prepare you for the constant pace of it. Particularly now that the pace has changed so much. It’s hard for anyone to handle."
